A graph has seconds after water began leaking on the x-axis, and volume of water in cup (milliliters) on the y-axis. A line goes
through points (4, 8) and (6, 1). The graph shows the volume (y) of a cup of water (in ml). The cup has a small leak and the volume of water is decreasing at a constant rate each second (x). The situation can be expressed as a linear equation. Which values are correct for the slope and the y-intercept of the graph?
m = –1.5, b = 22
m = –3.5, b = 22
m = –3.5, b = 420
m = –1.5, b = 420
For this case we have the following relationship: P1V1 = P2V2 Clearing volume 2 we have: V2 = (P1 / P2) * (V1) Substituting values we have: V2 = (5.1 / 1.0) * (350) V2 = 1785 mL Answer: this gas would occupy 1785 mL at 1.0atm
